PAPER-MAKING MACHINERY.

Application filed September 13, 1923.

To all whomz't may concern:

.Be it known that I, WALTERVVERNER, a citizen of the United States,residing at Hoosick Fallsfin the county of Rensselaer e and State of NewYork, have invented certain new and useful Improvements in Paper- MakingMachinery, of which the following is a specification.

rl`his invention relates to paper making lo machinery.

The object of this invention is to provide a simple but effective meansfor fitting and locking a one piece cast metal shell liner in the shellof a Jordan engine.

The Jordan engine, commonly called a Jordan, consists of a stationaryshell conical in shape and bored on the inside on a taper, the insidebeing lined with knife bars which coact with other knife bars mounted 2oon the periphery of arotating conical core or plug mountedconcentrically with the en ine shell, and adjustable axially.

he Jordan shell is usually lined with knife bars which are held in placein a spaced relation to each other by means of wooden space fillers ofshell woods, and wedges. A series of metal ribs or bars are sometimesbolted inside the shell before the lining is inserted, to assist inholding the,

lining against displacement due to torsional strains.

When handling certain kinds of paper stock the treatment of which causesmore than! the usual wear on the knife bars and so makes necessary thefrequent relining of the Jordan, a more substantial and more easil)7installed shell liner is desirable. One type of shell liner which hasbeen used t0 some extent being a sectional cast metal liner having ribsor knife bars cast integral therewith, the sections being in the form ofsplit conical rings which are wedged, or wedged and bolted into theshell in various manners. rllhis type of shell liner while moresubstantial and more easily installed, has certain disadvantages whichare hard to overcome. The sections beingl cast split conical rings arefastened in place by means of wedges driven between or into the split soas to 50 expand the section until it becomes fast in the shell. Boltsare also used to expand the Section and assist in holding it in place.With this style of liner it is almost impossible to install and maintainthe various sec- Serial No. 662,402.

tions of the liner in accurate alignment and perfect concentricity, andwhen perfect alignment and concentricity is not maintained uneventreatment ot' the stock passing through the engine and uneven wear onthe knives will result therefrom.

A one piece cast metal 'shell liner, the knives cast integral therewith,is without ldoubt the most substantial and most quickly installed of thevarious Jordan shell liners, but it has been found in practice thatthere is very frequently "a slight difference in the taper on which theshells are bored and that to properly fit a new one piece lining into anold shell` it is' necessary to take accurate measurements of the shelland to use great care in turning the lining so to insure a proper lit inthe shell. The turning of each lining to fit a 4particular shell, andthe care necessary to produce the exact taper required adds greatly tothe cost of re-lining shells with one piece cast liners.

To overcome the necessity for such accurate work, which is expensive,and provide a onepiece ca'st metal Vshell liner and locking means whichwill be interchangeable in a given size of Jordaml have devised a onepiece cast metal shell liner provided with a self centering shimminglocking ring. rlhis device, and-the method in which it is installed in ashell .is illustrated in the accompanying drawings,i which:

Fig. 1 is a longitu inal section through the shell and lining of aJordanengine, the plug body and some of the plug knives being shown in place.

Fig. 2 is a section, on a larger scale, ofy a fragment of the shell of aJordan engine equipped with my improved one piece cast shell liner andself centering locking ring.

Fig. 3 is a section, on ay still greater scale, through a' fragment of aJordan shell, my improved shell liner and liner lock, and shows 'theself-centering shimming locking ring b fore being forced t5 a seat.

The same reference characters refer to the 100 same parts throughout theseveral views.

Referring to the drawings, A represents the shell of a Jordan engine, Bmy improved one piece cast shell liner, C my self centering shimminglocking ring, D the knife bars or ribs of the liner, E the plu body, Fthe plug shaft, G the plug knives, lgl the plug woods, K one of theusual attaching bolts which may be used to assist in resisting torsionalstrains on the liner, kand r1, r2, r3, finish rings formed on theoutside of the shell liner C.

In turnin ofl' the finish rin s I referably use a s ightly le includeang e than that Which is standard for the bore of a Jordan shell, andthe finish ring at the large end of the liner (r1) I turn straight orparallel with thel aXisf of the liner for a portion of itsV length.

The inside of my self centering shimming locking ring C, is alsosubstantially parallel with the axis thereof, and the inside diameter isthe same or but slightly in excess of the diameter of the straightportion of the finish ring r1. The outside of the ring C is turned onsubstantially the same taper as is the liner.

To install my improved liner in the shell of a Jordan it is onlynecessary to insert the liner in the shell until the small-end finishring r3 comes to a seat against or in the shell, drive to a seat theself-centering shimming locking ring, and put in place any bolts whichmay be used to resist torsional strains. Any variation in the diameterof the shell will be compensated for by the ring C, for shouhd thediameter of the shell be ygreater than standard. and where there is adifference it is usually an oversize, the ring C, will drive in until itreaches a point atwhich the inside diameter of the shell equals thestandard and will fit it closely. When there is considerable oversize inthe shell and the ring has to be driven in for more than the usualdistance in order to reach a. seat, the outer corner of the thin edge ofthe ring will first contact with the inside of the shell in advance ofthe point at which it will reach its pro er seat,'When this occurs thefinal driving o the ring will cause the thin edge thereof to be crimpedover the ridge formed at the meeting of the straight and taperedportions of the largest finish ring. f

It is of course obvious that such a, locking ring as I make use of isself-centering and that driving such a ring in between the liner andtheshell has the same effect as shimming out or increasing the diameter ofthe liner at the large end.

I preferably make use of the usual attaching bolts such as that shown atK.

1. In a Jordan engine, a conical liner the small end thereof adapted toseat against the engine shell the large end thereof wedged into and heldconcentric in said shell by a ring of Wedge-shaped cross section drivenbetween said shell and said liner.

2. In a Jordan engine, a one piece conical liner the large end thereofwedged into and held in concentric position by means of a ring ofwedge-shaped cross section driven in between said liner and said shell.

In testimony whereof I have aflixed my signature.
